BUILDING CONSTRUCTIN.

To all `iti/wm t may concern Be it known that I, FRANK R. HAHN, a citizen of the United States, residing at Decatur, in the county ol Macon and State of Illinois, have invented certain new and useful Improvements in Building Constructions, of which the following is a specification.

My invention relates to improvements in building construction and more particularly to a peculiar form of unit especially adapted for small structures such` as garages, conservatories, pantries, farm buildings and the like, which are usually auxiliary to main buildings or structures,` these structures being comparatively lightV and having a comparatively small amount of weight above.

l The principal object of this invention is the provision of such a construction composed of a plurality of elements or units formed or cast of cement, concrete or other suitable plastic material and arranged to be assembled and held together to form a complete structure,provision being made so that the structure may beereoted for temporary or permanent purposes, the elements being securely locked and held together.

Another object of this invention is the provision of a slab member of comparatively thin construction and arranged to interit with other slabs. each slab having extensions located near the interiitting ends thereof which are adapted to cooperate with correspending extensions on the adjacent slabs so as to form a substantially hollow column or post which may be utilized to receive a temporary securing means or which may be iilled with cement, concrete or otherl suitable plastic material in the event that the building is to be permanent.

To the accomplishment of the foregoing and such other objects as may hereinafter appear my invention consists in the construction, combination and arrangement oit parts hereinafter described and then sought to be delined in the appended claims, reference being had to the accompanying' drawingr forming a part hereof and which shows merely for the purpose of illustrative dis- Specification of Letters Patent.

closure a preferred embodiment of myinw vention, it beingexpressly understood .however that various changes may be made in practice within the scope of the claims without digressinpr from in7 inventive idea.

In the drawings Fig. l is a perspective view from the inside ot the corner ot a structure composed ot a plurality of elements embodying my invention. Y

Fig. 2 is a perspective view of one of the elements shown in Fig. l and the end portion of the next adjacent element.

Figure 3 is a detail plan view of a corner of the wall.

In building operations.

it has quite often been found advisable and desirable to erect additional or auxiliary structures of comparatively small height and weight. which do not have to be as substantial or as well built as main structures. examples of such structures are sheds, garages, pantries and buildings of that sort, and usually the cost is a considerable item. To accomplish the erection of such a structure at a minimum cost I have devised a construction illustrated in this application which will serve the required purposes, beinp; of suiiicient strength and rigidity. 'i

Referringnow to the drawings, the numeral l designates a slab or unit constructed to embody my invention, it being expressly understood that this 'form and shape oi unit is disclosed merely to illustrate my invention, and that the same may be carried out by means of slabs or units of various other forms. shapes and sizes. This slab or` unit l. is preferably provided along one side with a groove 2 and on the other side with a corresponding tongue 3 so that adjacent slabs or' units will intertit along their top and bottom edges. At each end ot the slabs or units I provide a reduced portion l and headed portionl 5 which are arranged to inter'it with a corresponding headed portion 5 and reduced portion 4f on the adjacent ends ot the next slab or unit, as illustrated in Fig. 2, whereby the adjacent slabs or units are securely locked and connected together. This construction is substantially the same at the corners except that the reduced portion is made in the lorm of steps 7 and 8 with the head 9 on the end, this iitting with a correspondingly and complementary shaped end part o n the interlitting corner slab or unit.

Adjacent the end o'li each ot these slabs or units I provide the inwardly extending flange l0 having the right angled 'llaiige ll, those on adjacent units being adajjited'to cooperate, as clearly shown in Fig. l, in the assembled wall to 'form a hollow post or column l2. The same idea is utilized at the corner but merely by the formation of the laterally extending ilaiige member l?) near the end ot each of the corner slabs or units which will cooperate with the adjacent flange toprovide the hollow corner post or column iet, as clearly shown in l.

Nhen the structure is erected for temporary purposes the same may be assembled by the useci the bottom plate l5, and the top plated@ connected by the elongated bolt or rod 17 ,connected at one end by the loop it and at the other end by nut 19,. rlvhis merely exemplifies one `torni .o'l5 means whereby the structure may be readily dissembled when it is desired to take the same down. rlChe construction ormsa post and a connecting` web at each vertical series of units or slabs and as the posts are hollow, they may be filledwith any suitable material il' desired. Also, while reinforcing rods or wires l are illustrated in Figure 2 of the drawings, any other suitable reinforcement may of course be employed.

d In addition to the interlocking` eiidsoiithe slabs, I may utilize additional securing` means including hook members E20 which engage'the parts 2l o't reiii'lorciiig rods or wires which are exposed by recesses 22m the flanges 10. One or both of these sc-,fcuring` means may be used, as desired.

It rs, therefore, seen that I have provided means for erectingstructuies composed of various pre-cast'uiiits which are strong and rigid, without the necessity el utilizing` separate studs, posts or the like and which may be built temporarily or knocked down, fmfl Which may bebuilt tor permanent purposes.y

`I`his application is a .division of anapjiilicatripn ledby me on. the 2nd day of March, llrxbearing Serial No.l 151,906 .for concrete building construction.v
